ヨイント金物に関する。[Detailed description of the invention] The present invention is designed for three-dimensional trusses, more specifically, for three-dimensional trusses, which are used when constructing reinforced concrete deck slabs, and for plane trusses that are arranged in an inclined manner. The present invention relates to a joint hardware for connecting a joint with a connecting member disposed laterally.
鉄筋コンクリート造床版は一般に、下階の既設床版上に
支保を立て、該支保上に型枠を配置してこれに支持させ

保障の限りでなく、施工能率も極めて悪い。According to this conventional construction method, the shoring cannot be removed until a certain period of time has elapsed after the concrete is placed, at least until the slab has enough strength to support itself, and as a result, the shoring can become stuck. If finishing work cannot be carried out on the lower floor and one attempts to do so, the safety of the work cannot be guaranteed and the efficiency of the work will be extremely poor.

版施工方法を開発し、これは別途特許出願されている。In view of the above, the present applicant has constructed a plurality of plane trusses, each consisting of an upper chord member, a lower chord member, and a lattice arranged between them, so that the upper chord members and lower chord members of adjacent planar trusses are close to each other and parallel to each other. arranged at an angle to
The planar truss is joined by upper and lower connecting members arranged in a direction orthogonal to the upper and lower chord members so as to pass through the intersections of the upper and lower chord members with the lattice, respectively, to form a plate-shaped three-dimensional truss. concrete forming, attaching formwork to the underside of the three-dimensional truss, placing the form-supporting three-dimensional truss on the upper end of a beam or wall of a building, and then pouring concrete slabs. We have developed a method for constructing floor slabs, and a separate patent application has been filed for this method.
本考案は前記したごときコンクリート造床版を施工する
際に用いられる立体トラスを能率的に組立てることので
きるジヨイント金物を提供することを目的とする。The object of the present invention is to provide a joint hardware that can efficiently assemble a three-dimensional truss used when constructing concrete deck slabs as described above.
ところで、前記した立体トラスの組立てに際して、各交
点を各連結材には、それぞ1本の異形鉄筋を配筋する場
合と、径を小さくして2本の異形鉄筋を配筋する場合と
があるが、本考案は後者のように、2本の異形鉄筋を連
結材として配筋した場合の、該連結材と弦材との結合を
行うジヨイント金物に係り、ボルトを挿通させる孔を中

子連結材とをそれぞれ前記2つのの受は金具で挟持して
結合するように構成したことを特徴とする。By the way, when assembling the above-mentioned three-dimensional truss, there are two cases: one case in which one deformed reinforcing bar is arranged at each intersection point and each connecting member, and the case in which two deformed reinforcing bars with a smaller diameter are arranged. However, the present invention relates to a joint hardware that connects the connecting material and the chord material when two deformed reinforcing bars are arranged as connecting members, as in the latter case, and a hole for inserting the bolt is placed in the center. The two receivers include a metal fitting, a bolt inserted into the hole, and a nut to which the bolt is screwed, and two upper chord members and two upper tie members or two lower chord members and two lower chord members. The connecting member is characterized in that the two receivers are configured to be sandwiched and connected by metal fittings.
以下具体例に基づいて説明する。This will be explained below based on a specific example.
本考案ジヨイント金物の使用対象とされる立体トラス1
0は第1図に示すように、上弦材11と下弦材12と両

面トラス14,14−一とを結合してなるものである。Three-dimensional truss 1 to be used for joint hardware of the present invention
0, as shown in FIG. 11, 11 and the lower chord members 12 and 12 are arranged at an angle so that they are close to each other and parallel to each other, and on the other hand, the upper chord member 11 and the lattice 13 of each plane truss 14, and the lower chord member 12 and the lattice 13, respectively. 2 so as to pass through the intersection
The two upper connecting members 15 and the two child connecting members 16 are arranged in the lateral direction of the plane truss, that is, in the direction perpendicular to each chord member, and at the joint part 17, each connecting member 15, 16 and the two child connecting members 16 are arranged in the horizontal direction of the plane truss, that is, in the direction orthogonal to each chord member. It is made by combining one and the other.
この場合、ジヨイント部を溶接によって結合することも
可能であるが、溶接熱によって立体トラスが変形するの
で、その矯正を必要とするなど、必ずしも作業性が改善
されることとならない。In this case, it is also possible to join the joint parts by welding, but since the space truss is deformed by welding heat, it is necessary to correct the deformation, and the workability is not necessarily improved.
また、例えば連結材に前もってスタッドボルトを植設し
ておき、このスタッドボルトを利用して、両端が折り曲
げられた金具を隣接する弦材に締め付けることも考えら

価が高くなってしまう。Also, for example, it is conceivable to install stud bolts in advance in the connecting member and use these stud bolts to tighten a metal fitting with bent ends to the adjacent chord members, but it is difficult to install stud bolts. increases, resulting in a higher unit price.
そこで本考案は前記結合部を以下に述べるジヨイント金
物によって結合するこにより、溶接やスタッドボルトを
用いる結合方式によれば起こるであろう不都合を解消す
るものである。Therefore, the present invention solves the inconveniences that would occur if the connection method uses welding or stud bolts by connecting the connection portions using joint hardware described below.

。As shown in FIGS. 2 to 5, the joint hardware of the present invention has two receivers, a metal fitting 20 and 21, and a bolt 2 that is inserted into bolt insertion holes 22 and 22 provided in the metal fitting.
3. A nut 24 is screwed onto this bolt 23.
受は金具20.21は実質的に同形状のもので、中央に
孔22を有し、その両端部20a、21aは折り曲げて
底形しである。The metal fittings 20 and 21 of the receiver have substantially the same shape and have a hole 22 in the center, and both ends 20a and 21a are bent to form a bottom shape.
この折り曲げ端部を備えることにより、平面トラスおよ

示したのと全く同じジヨイント金物を使用できる。In addition, what is shown is upper chord members 11, 11 and upper tie members 15.
15, but the lower chord material 12
.. The joint hardware for joining 12 and the child connecting members 16 and 16 is, for example, the joint hardware used in the form in which the lattices 13, 13 are inclined upward in FIG. can be used.
受は金具20.21は平面形状が長方形であるが、その
他正方形など任意である。The metal fittings 20 and 21 of the receiver have a rectangular planar shape, but may have any other shape such as a square.
以上のように構成した本考案ジヨイント金物の使用に当
たり、2つの上弦材11,11に端部20at20aが

22.22にボルト23を挿通し、必要に応じてワッシ
ャを当てナツト24により締め付けて結合する。When using the joint hardware of the present invention constructed as described above, the bracket 20 is placed so that the ends 20 at 20a are opposed to the two upper chord members 11, 11, and the two upper chord members 1
5.15 The receiver is attached to the metal fitting 21 on the lower side of the metal fitting 20, and the said receiver is in a direction perpendicular to the metal fitting 20, and moreover, the end portion 21at21a abuts against the upper binding material, and both the receivers are connected to the holes 22, 22 of the metal fittings 20, 21. A bolt 23 is inserted into the hole, a washer is applied as necessary, and a nut 24 is tightened to connect the screws.
この結合の結果、ボルト23は2つの上弦材と2つの上
達結材とで囲まれる空間に位置するので、受は金具20
.21を介して各部材に均等な締付力を付与することと
なる。As a result of this connection, the bolt 23 is located in the space surrounded by the two top chord members and the two top tie members, so the receiver is attached to the metal fitting 20.
.. 21, an equal tightening force is applied to each member.
下弦材12.12と子連結材16.16との結合も全く
同じである。The connection between the lower chord member 12.12 and the child connecting member 16.16 is exactly the same.
なお前記例では、ジヨイント金物はボルトの両側に2つ
の上弦材を配置したものの結合として用いているが、例
えば立体トラスの最も外側に位置するジヨイント金物は
ボルトの片側にのみ上弦材を配置する。In the above example, the joint hardware is used to connect two upper chord members arranged on both sides of the bolt, but for example, the joint hardware located at the outermost side of the three-dimensional truss has the upper chord arranged only on one side of the bolt.
この場合、上弦材がない方の側には、スペーサとして適
宜に部材を配設してやれば、同じジヨイント金物の使用
が可能である。In this case, it is possible to use the same joint metal fittings as long as a suitable member is placed as a spacer on the side where the upper chord member is not present.
以上のように構成した本考案ジヨイント金物によれば、
2つの受は金具にボルトを挿通し、ボルトにナツトを締
め付けるだけで2つの上弦材と2つの上達結材または2

の結合は実質的に剛接合であるので、専門工を必要とし
ないばかりか仕上り精度も高い。According to the joint hardware of the present invention configured as described above,
The two receivers can be used by simply inserting the bolts into the metal fittings and tightening the nuts onto the bolts.
The two lower chord members and the two child connecting members can be joined together, and since the joining is essentially a rigid joint, not only does it not require specialized workers, but the finishing accuracy is also high.
しかも受は金具はプレス成形によって量産できるので、
単価を安く抑えることが可能である。Moreover, the brackets and metal fittings can be mass-produced by press molding.
It is possible to keep the unit price low.
